Anti-CD33 (Lintuzumab)-MC-Vc-PAB-DMEA-(PEG2)-duocarmycin SA ADC (ADC-W-817)

This ADC product is comprised of an anti-CD33 monoclonal antibody conjugated via a MC-Vc-PAB-DMEA-(PEG2) linker to duocarmycin SA. The duocarmycin SA is targeted to certain cancers by immunerecognition and delivered into cancer cells via receptor mediated endocytosis. Within the cell, duocarmycin SA binds to DNA, causes DNA damage.

 ADC Target

  • Name
  • CD33
  • Alternative Names
  • CD33; CD33 molecule; CD33 antigen (gp67); myeloid cell surface antigen CD33; FLJ00391; p67; sialic acid binding Ig like lectin 3; SIGLEC 3; SIGLEC3; gp67; sialic acid binding Ig-like lectin 3; sialic acid-binding Ig-like lectin 3; SIGLEC-3;
  • Target Entrez Gene ID
  • 945
  • Overview
  • CD33 or Siglec-3 is a transmembrane receptor expressed on cells of myeloid lineage. It is usually considered myeloid-specific, but it can also be found on some lymphoid cells. It binds sialic acids, therefore is a member of the SIGLEC family of lectins.

 ADC Antibody

  • Overview
  • Humanized Anti-CD33 IgG1-kappa antibody, Lintuzumab
  • Generic name
  • Lintuzumab
  • Host animal
  • Mouse
  • Species Reactivity
  • Human

 ADC Linker

  • Name
  • MC-Vc-PAB-DMEA-(PEG2)
  • Description
  • Peptide linkers, belonging to Enzymatically cleavable linkers, combine greater systemic stability with rapid enzymatic release of the drug in the target cell. The scission of peptidic bonds relies on lysosomal proteolytic enzymes, which have very low activities in blood due to endogenous inhibitors and the unfavorably high pH value of blood.

 ADC payload drug

  • Name
  • duocarmycin SA
  • Description
  • Duocarmycins SA belong to the minor-groove-binding DNA-alkylating agents (DNA MGBA). The natural duocarmycins are isolated from the culture broth of Streptmyces sp and a series of derivatives has also been synthesized.
